INDEX

Vigyan Ashram has designed & developed a

“Sand filter” for schools / small houses/

bungalows and remote locations. Users of the

manual will be able to build their own Sand filter

using this manual. All the Bills of Materials

(BOM) and dimensions of the systems are given in

the design. We have provided designs files drawn

using Solidworks along with this manual. Users

are suggested to read the manual carefully along

with the site conditions before fabrication of the

unit.

1. 1. Introduction

To share standardized design of Sand filter suitable

for small bungalows, hamlets, schools and institutes.

Design to be made available online for students,

peoples to build Sand Filter for their uses.

2. 2. Purpose of Manual

During fabrication of the system we should use safety

equipment such as hand gloves, shoes and glasses.

(And as appropriate)

3. 3. Safety Instructions

We have developed a Sand Filter-Supplement for water

purifier system. This system is deployed after a storage

tank of water & before water filtration system. It having

2” PVC pipe structure & 2” standard piping connections.

This structure contains layers of stones(150gm),

charcoal(200gm), gravels(200gm) and fine sand(250gm)

respectively. We are able to reduce particulate matters,

turbidity of output water from storage tank. It is act as a

pre water conditioner. It will helpful to increase the life of

water purifier.

The detail view and BOM are shown in below:

Method Used: Upward water flow

Compact System

Use:

o Drinking water production

o Swimming pools

o Groundwater treatment

o Fruit and vegetable processing industry

NOTE: There is no conclusive evidence that produce

grown hydroponically are more nutritious or healthier

than produce grown by any other method.

Sand filters are used as a step in the water treatment

process of water purification.

To remove or to reduce the remaining impurities still

further, and to produce safe water, the water is filtered

through the beds of fine granular material, such as sand,

charcoal etc.

Filtration may help in removing colour, odour, turbidity

and some pathogenic bacteria from water.

The unfiltered water is distributed in the top of the sand

filter and will slowly sink through the filter bed.

This filter bed consists of sand, gravel or another filter

medium. The small pores ensure that the dirt particles are

not able to pass through and retain the dirt particles.

9. 8. How it works? – Sand Filter

10.

Step 1: PVC pipe cutting

Step 2: End Cap cutting

Step 3: Filter material preparation

Step 4: Pipe fittings assembly

9. Step by Step installation

11.

Make holes on End Cap properly at specified

positions.

Plumbing as shown in the diagram of pipe connections

must be proper to avoid leakages from joints.

Sand Filter casing should be leak proof.
